Therefore, most of Chinese medium-and-high grade cars are equipped with headlight cleaning apparatus. Especially, a headlight such as a gas discharge lamp is easy to be contaminated during running process and causes glare for a driver counterpart, and further might causes accident. Therefore, to equip a cleaning apparatus on a headlight of a gas discharge lamp is necessary; meanwhile, China has already compulsorily executed provision that a high-brightness light source must be equipped with a headlight cleaning apparatus.
- So far, lots of relevant technologies are disclosed, such as the Japanese patent with publication No.
JP2003285723 - To prevent the invasion of rainwater, impurities and so on from entering into said headlight cleaning apparatus, said cleaning cylinder is sealed by seal components inside and outside. However, due to the interior and exterior seals, air can't cross the space between the piston and the seals freely. Additionally, with the going in and out of air, flow resistance (pressure loss) is increased dramatically, which results in cleaning cylinder hard to move freely relative to other fixed parts (such as the fixed piston).
- To deal with above problems, said Japanese patent provided a headlight cleaning apparatus which can not only prevent the invasion of rainwater, etc, but can make the cleaning cylinder move freely relative to other fixed part (suchasthefixedpiston) .
- From disclosed content of said Japanese patent, the cleaning apparatus is equipped with the retractable sprayer; the piston partially inserted into the opening part of the cleaning cylinder and slideably arranged in the cleaning cylinder; the fixed piston which is arranged outside (inside) the cleaning cylinder and provided with the fixing part fixed on the fixed part of the vehicle body; the augmenter arranged between said piston and the fixed piston and capable of pressing the retractable sprayer to one side of the fixed part; the inner cylinder sleeve which is slideably inserted into said fixed piston and fixed on one end of the cleaning cylinder for closing said opening; and the connection vent that can discharge air in the cleaning cylinder. The augmenters (springs) are mounted on the sprayer and the fixed piston respectively, and said sprayer can be slideably inserted into one end of said fixed piston. Because the aim of the invention of said headlight cleaning apparatus is to prevent the invasion of rainwater, etc, the invention of said headlight cleaning apparatus focused on binding and matching between constructional elements and the vehicle body. Therefore, it is obvious that the cleaning apparatus of the contrasting invention is more complex in structure and complicated in manufacturing.

Moreover, the cleaning apparatus of the invention is in light and handy structure and requires small plaque size and lower assembly requirement. The headlight cleaning apparatus is especially suitable for cleaning a gas discharge lamp.
- To realize above purposes, the technical scheme of the invention is as following:
- A vehicle headlight cleaning apparatus comprises a cylindrical casing body, a transmission guide rod arranged in the cylindrical casing body for the cleaning solution flowing, a nozzle assembly connected with the upper end part of the transmission guide rod, and a compression spring arranged in the cylindrical casing body; and the cleaning apparatus is characterized in that the bottom of the

compression spring 7 is positionedbetween thecylindrical casing body 5 and the exterior cylinder wall of thetransmission guide rod 8. Both ends of thecompression spring 7 are fixed on the inner side of the upper end part of thecylindrical casing body 5 and aspring fixing base 10 of the movable seal valve respectively. The lower end of the cylindrical casing body is provided with the movable seal valve. The movable seal valve is slideably arranged at the lower end part of thetransmission guide rod 8 which is connected with the transmissionguide rod base 9 in a propping mode; the movable seal valve comprises aspring fixing base 10 and amain seal ring 11 which are arranged at the bottom end inside the cylindrical casing body and sleeved on the lower end of thetransmission guide rod 8.
a seal gasket (4) is arranged on the upper end part outside said cylindrical casing body (5), and the interior bottom of the seal gasket (4) is provided with an exhaust groove (4-3). - The vehicle cleaning apparatus based on the invention has the following cleaning process.
- If the cleaning apparatus does not work, the movable seal valve is propped and tightly attached to the upper end of the transmission
guide rod base 9 under an elastic force of thecompression spring 7 and makes the interior of thetransmission guide rod 8 and the movable seal valve in a watertight state. - If the cleaning apparatus is started, under the pressurizing, cleaning solution flows into an empty space consisting of the transmission
guide rod base 9, thecylindrical casing body 5 and themain seal ring 11 through the cleaning solution inlet 13-1 of the cylindricalcasing body base 13. To increase the pressure of the cleaning solution, with the increasing of the interior pressure of the cleaning solution, the compression force of thecompression spring 7 and the friction force between themain seal ring 11 and the interior wall of the cylindrical casing body is overcome, therefore, thetransmission guide rod 8, thenozzle holder 3 and the movable seal valve is driven to move upwards to the nozzle end. - The interior pressure of the cleaning solution increases continuously, the
transmission guide rod 8 keeps on moving upwards to the nozzle end till the lug boss 8-1 of thetransmission guide rod 8 props against the inner wall of the top end of the cylindrical casing as shown infigure 7A . At the time, thetransmission guide rod 5 stops moving upward to the nozzle end. - The interior pressure of the cleaning solution increases continuously, the pressure is large enough to overcome the compression force of the
compression spring 7, the friction force between themain seal ring 11 and the inner wall of the cylindrical casing body and the friction force between themain seal ring 11 and the outer wall of the transmission guide rod, the movable seal valve moves upward and then is opened, at that time, the pressure of the cleaning solution and the spring force of the compression spring reaches a balance, which makes the movable seal valve maintain the open state, as shown inFig. 7B . - The cleaning solution flows into the
transmission guide rod 5 from the opening 8-3 on the lower end of the transmission guide rod, flows through the transmission guide rod and into thenozzle holder 3, and finally is sprayed out from thenozzle 1 to realize the cleaning action. - After cleaningisfinished, due to the disappear of the cleaning solution pressure, under the function of the elastic force of the
compression spring 7, the movable seal valve firstly retracts back and closes to the transmissionguide rod base 9, at that time, it goes back a seal state. And then, under the function of thecompression spring 7, thetransmission guide rod 8 overcomes the resistance of the cleaning solution and the friction force between themain seal ring 11 and thecylindrical casing body 5 to retract back into the casing till returning to the initial state. - Until then, the whole cleaning process is finished.
- The vehicle headlight cleaning apparatus of the invention realizes extension of the transmission guide rod and opening of the movable seal valve with the aid of change of water pressure and different elastic forces of the compression spring in different compression lengths. Therefore, the headlight cleaning apparatus has simple structure, high efficiency and reliable operation in headlight cleaning.

components component - Next, the vehicle headlight cleaning apparatus of the invention is further described in details by combing the following attached figures and the embodiments.
- A vehicle headlight cleaning apparatus comprises: a casing which is consisted of a main
cylindrical casing body 5 and acasing base 13 connected with the main cylindrical casing body, aseal component 12 is arranged between the maincylindrical casing body 5 and thecasing base 13, thebase 13 is provided with a cleaning solution inlet 13-1 and steps for fixing a transmissionguide rod base 9. - A
transmission guide rod 8 is of a cylinder structure and provided with openings on the front and the rear sides; the front opening is in a shape of a regular hexagon, which has the function of guiding and is matched with anozzle holder 3; the rear opening allows the entry of cleaning solution while a movable seal valve is opened and is fixedly connected with the transmission guide rod base. The rear end of thetransmission guide rod 8 is provided with a lug boss 8-1 which has position limiting effect. - The lower end of the
transmission guide rod 8 is equipped with the movable seal valve, and said movable seal valve comprises aspring base 10 and amain seal ring 11 and can slide freely on the bottom of the transmission guide rod. - The
main seal component 11 is of a ring shape, the inner wall of the main seal component is tightly attached with the lateral side of the bottom of thetransmission guide rod 8, the outer wall is tightly attached with the inner wall of the cylindrical casing body to move freely along with the movable seal valve, the bottom is tightly attached with the transmissionguide rod base 9 when the cleaning apparatus does not work. - The exterior of the

While the movable seal valve moves to the position as shown inFig. 7B , it stops moving and stays at the position as shown inFig. 7B , the work circuit of the cleaning solution in thetransmission guide rod 8 is opened, the cleaning solution flows into the transmission guide rod 8 (as shown inFig. 5 ) through an opening 8-3 at the lower end of the transmission guide rod and is finally sprayed out from the nozzle to clean the headlight. - When the cleaning apparatus finishes working, because the pressure of the cleaning solution disappears, the movable seal valve firstly restores to the position as shown in
Fig. 7A under the function of thecompression spring 7, then thetransmission guide rod 8 gradually retracts into thecylindrical casing body 5 till the position as shown inFig. 1 under the function of the movable seal valve. The whole cleaning process of the cleaning apparatus is finished. - Here, the fixed joint between the
nozzle holder 3 and thetransmission guide rod 8 is realized through a reverse-buckle 8-5 on thetransmission guide rod 8 and a reverse-buckle groove on thenozzle holder 3. - As shown in
